Abstract:

By analyzing the structural characteristics, installation process and technical advantages of theprefabricated partition wall, integrated pipeline, fire pump room and cold water room, the adaptationlogic of each system in the subway station scene is clarified, and the deep application of BIM technologyin the prefabricated construction of subway station is studied. Based on the Qianhai Station of the ultra⁃high underground space subway station, the BIM application practice of each prefabricated system issystematically expounded, including BIM⁃based modular parametric separation, prefabrication andinstallation of the whole process of collaborative management and control, and simulation optimization oftransportation and hoisting conditions. The research shows that the prefabricated construction driven byBIM technology shortens the construction period by 25% and reduces the on⁃site labor by 40% on thebasis of ensuring the quality of the project, which significantly improves the efficiency of greenconstruction.
